This paper describes a three-dimensional approach of microwave brightness temperature calculation of rain field using TRMM PR data. Calculations were made for the Stoke parameters by means of a vector discrete ordinate method toward twenty four directions in a three dimensional space. The results were compared to the TRMM TMI data to evaluate the validity of calculation. Introduction of wind-roughed sea surface model improved the correlation between the calculated and measured brightness temperatures.
